Lymphocytes Subgroup Typing Kit (Human)

Lymphocytes Subgroup Typing Kit is primarily used to determine the percentage of various peripheral blood lymphocyte subsets relative to total lymphocytes.

Human peripheral blood lymphocytes can be divided into three groups based on their biological functions and cell surface antigen expression: T lymphocytes, B lymphocytes, and NK cells. T lymphocytes primarily participate in cellular immune responses mediated by specific antigens and regulate immunoglobulin secretion by B lymphocytes. T lymphocytes can be further divided into helper/inducer T cells and suppressor/cytotoxic T cells based on their functions. NK cells, or natural killer cells, mediate cytotoxicity against certain tumor cells and virus-infected cells, independent of the presence of MHC class I and II molecules.

The Human Lymphocyte Subpopulation Analysis Kit, comprised of a series of dual-color fluorescently labeled antibodies, is primarily used to determine the percentage of various peripheral blood lymphocyte subsets relative to total lymphocytes, including mature T lymphocytes (CD3+), helper/inducer T cells (Th/i: CD3+CD4+), suppressor/cytotoxic T cells (Ts/c: CD3+CD8+), B lymphocytes (CD19+), and NK cells (CD3-CD16+ and/or CD56+). The Th/Ts (CD3+CD4+/CD3+CD8+) cell ratio can also be calculated.
